"I have just dipped into the future. We must be prepared for the worst."
Haunted by a shadowy watcher, the Doctor's bound for Logopolis in search of a new Chameleon cicuit for the Tardis. But unknown to the Doctor, a dangerous stowaway is on board — his arch enemy, the Master. Now in a new body, the Master is still bent on domination of the universe, and his plan could rock Logopolis, the keystone of life. Unless the Doctor can stop him, it could mean the unraveling of the causal nexus and the end of the universe itself!
This historic four-part adventure marks the end of the Tom Baker era, the fourth regeneration of Doctor Who.
